SPECIFICATION forming part of Letters Patent N0. 555,883, dated March 3, 1896. Application led June 20, 1892. Serial No. 437,372. (No model.)

To all whom t may concern.-

Be it known that I, CHARLES A. ANDERSON RAND, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in I'Iarvesters, of which the following is a full description, reference being had to the accompanying drawings, in which- Figure lis a plan view of so much of a harvesting-machine as is necessary to show my invention. Fig. 2 is a front elevation; Fig. 3, a stubble-side elevation; Fig. .4,a detail of the binding-table; Fig. 5, a sectional view of the head-hastening device; Fig. (i, a detail.

The object of my invention is to produce a harvester that shall permit its binding attachment to bind the grain upon substantially the saine level as the platform traveling conveyer.

As in this application I shall confine my claims to the means for handling the grain only, I show the binding devices only in so far as necessary to make clear their position and functions relative to the cutting and delivering apparatus, the reel, sheaf-carrier, and other parts being omitted.

In another application, filed March 2O and serially numbered 466, 961,the binding device will be shown, described and claimed in detail.

In the drawings the parts lettered A, joined as shown, constitute the main frame, which needs no description.

B is the cutting apparat-us, '3' the drafttongue, and B2 the brace connecting thc latter to the shoe of the grain-platform.

C is the supporting and driving wheel. It may have an axle with any of the usual forms of raising and lowering devices and be geared by means of a chain to the parts of the machine requiring to be driven. As far as the present application is concerned it is only necessary to begin at the crank-shaft D, from which the various moving parts receive their motion. It has at its forward end a sprocket-wheel D', by which the binder and conveying devices are driven, and the crank D2, by which the sickle is reciprocated.

E is the platform conveyer, made somewhat narrow, but extended rearwardly by means of the backboard E. The endless platform conveyer is moved at its stubble end by a roller, as usual in machines of the kind, which is shown in dotted lines in Fig. l. It is journaled at front and rear, and upon its forward end is the sprocket-wheelF.

F is a driving-chain thrown around the crank-wheel D. As the crank-wheel is given rotation the conveying-canvas is given movement in the proper direction to carry the grain that falls thereon continuously stubbleward. Overlying the delivery end of the conveying-canvas is the diagonal conveyer G. Reaching rearwardly from the front frame A is a stout bar A2. To the vertical part A3 of the front frame is secured the bracket a. (Shown in detail in Fig. G.) In this bracket is journaled a short shaft, keyed to which is the sprocket-wheel a. The chain F is also thrown around this sprocket-wheel. To the shaft is keyed the pinion a2. The bracket ais extended so as to form a journal-bearing a4 for the front end of the shaft of a driving-drum. (Shown in dotted lines in Fig.` Reference to Fig. l will show that this drivingdrum is diagonal relative to the line of advance of themachine. Its shaft is journaled at its rear end in the bearing d5, downreaching from the arm A2, the framework of which, a and a7, is so hung that it may rise and fall on the shaft as of the drum.

'lothe end of the drum-shaft is connected the bevel-gear as, adapted to mesh into the pinion a2. At the end of the diagonal conveyer nearest the driving-wheel is an idleroller journaled in the sides of the said frame. Around these two rollers is thrown an endless canvas G, having high slats. As the slats of this canvas are designed to strike into the swath of grain above, I provide, preferably, toothed bars, so that the grain maybe engaged as aggressively as possible. It is desirable to so provide that the slats of the diagonal conveyer shall not carry straws over on their return movement after they have delivered that moved by them, and hence to the arm. A2, I bolt a spring-rod a and extend it around the receiving end of the conveyer and underneath, as shown in Fig. 2, and finally turn it upward, as shown in Figs. l and 2. This will have the effect of clearing the slats of any straws that may adhere. If desirable, several such rods may be employed.

I have shown IOO one, al", as secured to the rear side piece a? of the diagonal co'nveyer. There may be as many, however, as the slats have notches. The shaft having the pinion a2 serves but as means for giving movement to the drivingdrum of the diagonal conveyer.v The latter may, however, be driven in various Ways.

H is a receiving-table onto which the straws are delivered and from which the packing devices of the binder take it.

Although this application has not to do with the binding devices, I have shown the packers of the same, because in my machine they become a part of the conveying devices and take the grain from the receiving-table H and carry it onward. Hence they form an element of an important combination of parts adapted to convey the grain,- give it direction, and deliver it finally into the binding-receptacle proper.-

The receiving-table is also extended deliveryward behind the main wheel so far as to form the frontal portion of the binder-table H2. Along the forward margin of the receivingtable H and the part I-l2 of the binding-table the butt-guides H and HB are placed. They are preferably formed by turning the sheet metal of which the parts of the table are formed upward. The guide H3 shields the forming bundle from the main wheel C.

I is the main frame of the binder attachn'ie1it,\'vhich attach ment need not be explained in this application only so far as the means fo'r supporting it, the packing devices, and the table are concerned.

J is the packer-shaft having double cranks, on whichthe packers j and j/ are carried. They are linked to the binder-frame by the connections 7'2 and 3'3, and by the cranks are given an orbital movement, as shown in dotted lines of Fig. 2. In order to give the packers and binding devices moven1`ent,a shaft K, preferably square,- is supported in the bracket a on the front frame A'. At its rear end it is journaled in a bearing K on the binderframe. At thefront end of the shaft is a sprocket-wheel K2, having a square eye to fit the shaft. Y

In order that the square shaft may be free to move fore and aft, the hub of the sprocketwheel is extended rearwardly, so as to form in effect the journal-bearing of the shaft, and the shaft passes through it. The sprocketwheel is driven in the direction indicated by the arrovr in Fig. 2; but in order that the packer-cranks may operate upon the grain properly it is necessary that they be revolved in the reverse direction. To accomplish this change of direction I provide a pinion k on the shaft K and a gear k 'on the packer crankshaft. The latter meshes in the main gear, also, of the binding attachment; but such fact may be ignored in this application.

The course of grain travel is shown by the line of arrows in Fig. l. The cut grain is received by the conveyer E in the usual manner and carried deliveryward until it passes under the diagonal conveyer, which, having aggressive slats, slides the swath slightly rearward, delivering it onto the receiver H. When it is forced to a position within reach of the packers they carry it in the direction of their feeding-movement and force it onto the binding-table proper. It is not my object to move the butts only, thus wheeling the straws by allowing the heads to remain stationary. This has often been done; but it is what I wish to avoid, because by the construction shown herein the swath or stream not being interrupted at any point, but simply given an oblique direction, the grain does not accumulate' at the rear stubbleward corner of the platform as it would if the swath was wheeled with that corner as a pivot.. To hasten the heads of the grain at that point, I provide toothed wheels L L, secured to the rear end of the platform-conveyer roller-shaft Z. The wheels are provided with backwardlydeflected teeth Z. These by their agitation of the straws and their movement in the proper direction tend to carry the heads of the grain forward onto the receiving-table II. The side frame-pieces A4 and A5, that are shown in Fig. 4, extend rearwardly beyond the wheel some distance.

M is a slide having the hooks fm m, reaching under the bars or fram e-pieces A4 and A5,

and the feet m2 and 'm3, which lie over the parallel bars of the main frame that are placed each side of the main wheel. To the slide M the rear end of the main frame I of the binder is connected by bolts in the lug z' cast upon the lower sleeve 7a2. At the forward end of the main binder-frame is the downreaching lug 1l', adapted to ride upon the side bar Al and also to hook thereunder, as seen in Fig. 2. The mainbinder-frame is practically supported immediately above this bar, and the latter takes all its Weight. The part of the support M that reaches to the right in Fig. 4 serves to steady the binder attachment.

N is a lever having a latch a adapted to engage a quadrant n on the main frame. Connecting the lever to the main frame is the rod n2. By these means the binding attachment is slid back and forth. One of the important features of my invention is this placement of the binding attachment. Reference to all of the figures will show that J[he main portion of the frame is more or less forward of the rear edge of the main wheel.. With the lever N thrown forward as far'as the quadrant n will allow, the binder will move as far forward as necessary to handle the shortest grain.

O is the rear portion of the binder-table, and it is connected to the forward part H2, as will be explained.

O' is a portion that, extending grainward, forms the rear part of' the receiving-table H. The forward edge of the part O laps over the part H.

o and o are bars, the former secured to the lugs 02 and o8 on the binder-frame, and the latter secured to the lug 04L of the slide M.

05 is a brace extending from the lug z' of the IOO .ing-wheel in any position of adjustment.

By placement of my binder-frame outside and alongside of the master-wheel, and placing the latter well forward in its frame, it is not necessary to deflect the swath of grain as far rearward as has heretofore been done. It will be seen that there is a gap between the end of the delivery-canvas E and the receiving-table H. If nothing were provided,straws would be carried therethrough, but by placement of the diagonal conveyer so as to sweep fully across the gap the straws are seized and carried thereover before they have time to fall through.

I am aware that it is not new to use an overlying conveyer; but I believe my arrangement to be new, and the functions performed by the parts because of the new arrangement to be new. It is not my purpose to advance the butts of the grain and thus wheel the straws into a new position, as has often been attempted, but, on the contrary, to change the direction of movement of the swath as a Whole and not change the linear direction of the straws.

I give my packers great scope of movement,

so that they may act not only as packers but reach well toward the grain and act as conveyers and take the grain from the receivingtable, along which the swath is moved diagonally, and carry it onward, but now in a direction transverse to the line of advance of the machine. In short, my device is intended to operate upon the grain and convey it in the path indicated by the arrows in Fig. l.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In combination, the main wheel, the cutting apparatus and grain-delivering conveyer abreast thereof, a binder in rear of said wheel, the receiving-table H between the deliveringcanvas and the said wheel, the overlying endless conveyer G having aggressive conveyingteeth adapted to engage the swath of grain and slide the straws backward while conveying them toward the binder, and said binder having conveying devices whose direction of action is parallel with the line of movement of the platform delivering-canvas, substantially as described.

2. The main wheel and a suitable supporting-frame, the cutting apparatus and platform delivering devices abreast of the said wheel, the receiving-table H, a binder in rear of the said wheel and having conveying devices adapted to force the grain into the binder, the overlying diagonal conveyingcanvas G, and the head-hastening feeders, all combined substantially as described.
